的挑战等。1.B细节理解题。根据第二段第一、二句可知,用3D打印机,一名厨师可在婚礼蛋糕上打印出复杂的巧克力图案和精美的装饰,这并非每个人都能做到,这要厨师多年的经验积累,但一台打印机可以很容易就做到。由此可知,3D打印技术在食品制作

方面节省了时间和精力。2.D推理判断题。根据第三段第四句“Someexpertsbelieveprinters...”可知,专家相信3D打印机可使用大量的藻类和草等可再生资源形成的水解胶体代替熟知的烹饪原料。3.B细节理解题。根据第四段中HodLips

on教授的话可知,食品打印能使得顾客打印出富含顾客个性化需求的营养成分,如维生素。因此,顾客不必吃昨天从超市买来的面包,而是随需烤制。4.C细节理解题。根据最后一段第三句“Ontopofthat,...”可知,尽管3D食物打印技术进展迅猛,但所需的大多数打印材料必须是干燥的才能使用,

这也就制约了食物打印技术的普及。Ⅱ.【解题导语】本文是记叙文。作者遭受的一场车祸改变了她的生活。1.B根据本空前后句内容可知,作者遭受了一场车祸,车上还有她的两个孩子,所以她当时应该感到“害怕(terrified)”。2.D根据本空后内容可知,“谢天谢地(Thank

fully)”,作者的两个孩子都安然无恙。3.B根据本句中的Despite可推测,尽管作者的左胳膊和脖子上有些擦伤,但是作者感觉“良好(fine)”,并无大恙。4.C根据上一句中的hospital可知,这里指“医生(doctor)”说作者有脑震荡。5.A根据本空

下一句内容可知,作者走路摇摇晃晃,所以她感觉自己失去了内部“平衡(balance)”。6.B根据本句中的“Ihaddifficultyincommunicating...”可知,作者跟人沟通有困难,她既记不住别人说的话,自己也“说(speak)”不清楚话。7.A根据本

句中的sunglasses可知,作者戴墨镜是为了保护“眼睛(eyes)”。8.D上段中的“ThefirstweekIfeltlike...”都是作者脑震荡后表现出的“症状(symptoms)”。9.D根据第一段中的

“...havingscratchesonmyleftarmandneck...”可推测,作者只是有些擦伤,“身体上的(physical)”伤并不明显。10.B根据本句中的“...peoplethough

tIhadrecovered...”可推测,人们以为作者痊愈了,尤其是她的外伤不明显,因此“忘记(forget)”了她正遭受的痛苦。11.C根据本空后的butIhadn’t可推测,人们以为作者已经摆脱了车祸带来的影响,“继续向前(moveon)”。12.A根据本空前的anxious及后面的st

resseating可知,作者焦虑而且“紧张(stressful)”。13.D根据本空后的内容可知,作者“决定(decide)”自我治愈。14.C根据上段中的“Igained25pounds...”可推

测,这里指作者“减肥(loseweight)”。15.B根据本文开头的“Lastyear,Ihadacaraccident.”可知,距离作者遭受那场“事故(accident)”已经将近一年了。16.B根据上句内容及本句中的still...but可推测,尽管作者还

受恐慌困扰,但是已经没有那么“频繁(frequently)”了。17.A根据本句开头的Although可推测,尽管作者恢复得不快,但是作者眼中的呆滞和绝望“消失(gone)”了。18.D根据下段中的mysecondlife可知,这里指作者获得了重新生活的“机会

(chance)”。19.D本句后的内容就是作者要“怎样(how)”重新生活。20.C根据本句中的“I’llbecomemychildren’sstrongestbacker...”可知,作者要做孩子们最坚强的后盾并告诉他们:无论发生什么

事情,“我”会“一直(always)”在。Ⅲ.【解题导语】本文是一篇说明文,主要介绍了竹子在中国的广泛应用及竹子所代表的含义。1.musical考查词性转换。根据词法知识可知,名词instruments前面应用music的形容词形式来修饰,表示“乐器”。故填mus

ical。2.application考查词性转换。分析句子成分可知,该空在句中充当主语,应用apply的名词形式application,表示竹子在科学技术方面的运用。故填application。3.led考查动词时态。根据

时间状语In251BC可知,此处叙述的是过去发生的事情,应用一般过去时;且lead与其主语LiBing之间是主谓关系。故填led。4.an考查冠词。playa/an...rolein为固定短语,意为“在……方面起……作用”;由于impo

rtant是以元音音素开头的,故用不定冠词an。5.made考查动词语态。bemadeof为固定短语,意为“由……制成”;此处表示世界上最古老的水管也是由竹子制成的,符合语境。故填made。6.successfully考查词性转换。此处应用suc

cess的副词形式修饰动词sank。故填successfully。7.until考查固定结构。根据语境可知,这个技术直到19世纪才传到欧洲。not...until...意为“直到……才”,符合语境。故填until。8.that考查强调句型。分析

句子结构可知,本句为“Itis/was+被强调部分+that...”的强调句结构,此处应用that,强调方式状语byusingthetechnology。故填that。9.one考查代词。根据常识可知,在中国文化中,竹子是植物中的“四

君子”之一。oneof意为“……之一”,符合语境。故填one。10.facing考查省略。分析句子结构可知,在when引导的时间状语从句中,face与其逻辑主语people之间为主谓关系,故此处应用face的动词-ing形式,从句中省略了主语people和

be动词are。故填facing。Ⅳ.WhenIwaseight,myfatherboughtmetheanewbikeformybirthday.Mybrotherofferedtoteachmehowtoride.Atfirst,he
